My dad is trying to wire a electric cook top...it has three wires (black, red, and copper). His junction box has four wires (black, red, white and copper). He first wired the black to black, red to red and copper to copper, he capped the white wire in the junction box. The cook top did not work. Then he connected the white wire with the two copper wires, and the cook top now works. So the question is will this connection work or will it cause a problem? And if it causes a problem what can he do to resolve it?
Hi There, This what I would do. The black and red wires from the cooktop are fine and can be connected to the black and red wires in the junction box. Check the copper wire from the stove and see where it is connected. It is probably a neutral wire used to supply 120 volts for a clock, lights or other control function. If that is the case I would exchange it for a properly sized insulated white wire. This white wire can be connected to the white wire in the junction box. Then: Connect the copper wire to a metal part of the cooktop to use as a ground wire. This wire can then be connected to the copper wire in the junction box. This would be a typical modern 4-wire 240 volt setup. Hope this helps, Al
What he did was correct to ground the white wire. You're good to go.
so it is new already == call the 800 number that is with the paperwork and ask the customer service to give you an explanation and email a wiring diagram ... best way to fix and have safety ...
